20090137179 | FIELD EMISSION DISPLAY AND METHOD OF MANUFACTURING THE SAME - A field emission display and a method of manufacturing the same are provided. The field emission display includes an anode plate where an anode electrode and a fluorescent layer are formed, a cathode plate where an electron emission source emitting electrons toward the fluorescent material layer and a gate electrode having a gate hole through which the electrons travel are formed, a mesh grid having an electron control hole corresponding to the gate hole and adhered to the cathode plate, and an insulation layer formed on a surface of the mesh grid facing the cathode plate, and spacers provided between the anode plate and the mesh grid so that the mesh grid can be adhered to the cathode plate due to a negative pressure existing between the anode plate and the cathode plate. | 05-28-2009 |
